Patients with long COVID-19 in the U.S. report far higher rates of brain fog, depression and cognitive symptoms than patients in countries such as India and Nigeria, according to a large international study led by Northwestern Medicine.
The authors note that the higher reported symptom burden in the U.S. may reflect lower stigma and greater access to neurological and mental health care, rather than more severe disease.
The study,the first cross-continental comparison of long COVID neurological manifestations, tracked more than 3,100 adults with long COVID evaluated at academic medical centers in Chicago; Medellín, Colombia; Lagos, Nigeria; and Jaipur, India.
Among patients who were not hospitalized during their COVID infections (the majority in the study), 86% in the U.S. reported brain fog, compared with only 63% in Nigeria, 62% in Colombia and 15% in India. Rates of psychological distress showed a similar pattern: Nearly 75% of non-hospitalized patients in the U.S. reported symptoms of depression or anxiety, compared with only 40% in Colombia and fewer than 20% in nigeria and India.
Researchers are investigating the prevalence and characteristics of long COVID infection between 2020 and 2025 across four academic medical centers. researchers included both hospitalized and non-hospitalized patients and assessed symptoms using standardized neurological, cognitive and quality-of-life instruments available at each site.

Long COVID affects millions of people worldwide and is characterized by symptoms persisting for weeks or even years after an acute COVID infection. Various studies estimate that 10-30% of adults infected with COVID develop long-term symptoms, with neurological and cognitive complaints among the most common and disabling.
as the authors note in the study, long COVID “affects young and middle-aged adults in their prime, causing meaningful detrimental impact on the workforce, productivity and innovation all over the world.”
